I just installed the Turner test pipes on my M3 with Eisenmann Race exhaust. I was afraid it was going to be raspy, but the sound came out perfect! The car became fairly louder, but the sound is amazing! It sounds less muffled without being too raspy. Also, theres a slight howl to it which i love.

As for the power, I didn't test it because its a really hot and humid day here and theres traffic everywhere. I'll test it in a few hours and be back to write my impressions.

So, Anyone looking for more power and a more exotic sound, I think these are really worth it!

Did you get the software as well of just the pipes?
I have an "E" Race as well, not sure i can take it any louder on the street. Looking forward to hearing it so post some audio sometime.

I took a quick video of the new setup. In the video it sounds more raspy than it really is. Sounds amazing in real life. Also the power bump is noticeable, even without a tune. My tires now chirp when they wouldn't before in this heat.

Here is my old video of Eisenmann Race only:

And the new one with Eisenmann Race + Turner Test pipes:

** For exact comparison go to minute 0:57 on both videos and compare before and after **

With the spacers did the CEL light come on yet. I have these but didn't install them as I didn't think they would work.

Dave, are you just driving with the CEL on? How do you like it without a tune?

Greg the car runs fine, like a scalded dog. The AFE Stg.2 intake and the TTPs make this car just ROAR. I do feel there can be some fine tuning with software. The stock muffler sounds pretty darn good with just the TTPs, not as aggressive at low revs as I would like but at high rpm's the car screams. It does have a hint of rasp.
